Artist David Hockney has a theory that some of the "old master" portrait painters secretly used cameras(!) to help them sketch their subjects. No, he's not saying that they had Polaroids or film. However, the camera obscura was available in the early 18th century, and the more practical camera lucida was invented in 1807. Did the great artists use these devices?
The date for this selection should be listed as January, 02000, in keeping with the long view of history, science, technology, and environment that the Long Now Foundation wants to foster.
In about 1637, a French mathematical genius named Pierre de Fermat wrote in the margin of his copy of Arithmetica by Pythagorus, that he could prove that there were no solutions to the simple variation on Pythagorus' Theorem, az + bz = czwhen a, b, and c are integers and z is larger than two.
Of course it is unreasonable to put together a list of the 100 most important books of the century. On the other hand, it is a lot of fun for a scientific bibliophile like me to think and argue about what ought to be on such a list.
I bought "Faster" because of talent the author had shown for rendering extremely complicated science for the interested layperson. "Chaos", published in 1987 was a wonderful book, and Gleick's next one, "Genius: The Life and Times of Richard Feynman", also won a National Book Award. (I haven't read that one, however.) "Faster" is a good book, but was nevertheless something of a disappointment.
Dava Sobel describes the correspondence to Galileo Galilei from his daughter, Virginia, who was a nun in the Convent of San Matteo, near Florence. Virginia, who took the religious name Maria Celeste, was a kind of apothecary in her convent, and she did her best to provide elixirs and pills to protect Galileo from the plague, along with weekly letters of news and encouragement.
In "The Sun in the Church", J. L. Heilbron describes the practical problem that faced the Church, in determining when Easter should be celebrated (the first Sunday after the first full moon after the vernal equinox) and how it supported research to resolve that matter (and also the problem of a church year that didn't match the solar one) without quite conceding that the earth orbits the sun.
This year's exhibit at the American Museum of Natural History of artifacts from the 1915 scientific expedition to Antarctica led by Sir Ernest Shackleton has been accompanied by the publication of Caroline Alexander's book, which includes the documenting photographs of Frank Hurley (some of which could be seen on the Museum's Web site).
Physicist J. Richard Gott of Princeton published a provocative article in Nature back in 1993, that described a simple method for the estimation of the likely lifetime of "things" on the basis solely of the length of their existence to date.
One of the mysteries of life is why organisms on our planet uses L-amino acids exclusively, when their mirror images have the same chemical stability.
